If 3t − 7 = 5t , then 6t = how do you solve this

Answers

$3t-7=5t \ \ \ |\hbox{subtract 3t} \n -7=5t-3t \n -7=2t \ \ \ |\hbox{multiply by 3} \n \boxed{6t=-21}}$

$3t-7=5t\n5t-3t=-7\n2t=-7|\cdot3\n\boxed{6t=-21}$

Step-by-step explanation: SJADHJISHDIAJDOQIWDJIQWFWQOFQWOFJQP

Answer:

y=1/2x-6

Step-by-step explanation:

y-y1=x(x-x1)

y-(-7)=1/2(x-(-2))

y+7=1/2(x+2)

y+7=1/2x+1

y=1/2x-6

Choose the three fractions that are less than 4/8 A) 1/2 B) 1/4 C) 5/8 D) 1/3 E) 1/8 F) 3/4

Answers

Answer:

B. 1/4

D. 1/3

E. 1/8

Step-by-step explanation:

4/8 can be represented as 1/2 or a half, therefore, find fractions that are less than half of the denominator.

Doing so will leave you with B, D, and E.

Half of 4/4 is 2/4, 1/4 is less

Half of 3/3 is 1.5/3, 1/3 is less

Half of 8/8 is 4/8, 1/8 is less

Dirk Nowitzki of the Dallas mavericks scored 44 points in a recent basketball game. He scored no 3-point shots, but made a number of 2-point field goals and 1-point free throws. He scored 30 times. How many 2-point shots did he make? How many free throws did he make?

Answers

x - 2-point field goals
y - 1-points field goals

2x + y = 44
x + y = 30

2x = 44 - y
y = 30 - x

2x = 44 - y
y = 30 - (22 - 1/2y)

2x = 44 - y
y = 30 - 22 + 1/2y

2x = 44 - y
1/2y = 8

2x = 44 - y
y = 16

2x = 44 - 16
y = 16

2x = 28
y = 16

x = 14
y = 16

x + y = 30
14 + 16 = 30
L = R

2x + y = 44
28 + 16 = 44
44 = 44
L = R
